| 摘 要： | 针对场次降雨水资源量评价与年尺度水资源量评价成果的不协同问题，通过分割前期降雨径流退水和年尺度基流等径流成分，提出场次降雨过程水资源量评价新方法，实现场次降雨水资源量的精细化评价。将该评价方法应用于潮白河典型区间流域，结果表明该方法具有较好的适应性，能够显著提高场次降雨水资源量评价成果的针对性和准确度，满足多时空尺度协同的水资源量评价需求。

| Abstract: | Aiming at the inconsistency between the results of precipitation water resources assessment and annual scale water resources assessment, a new evaluation method of precipitation water resource is proposed in this paper by splitting the runoff components such as antecedent precipitation recession and annual scale base flow, in order to realize the refined evaluation of precipitation water resources. The analysis results in the typical basin of Chaobai River show that the method has good adaptability, significantly improve the pertinence and accuracy of the assessment results of precipitation water resources, and fulfills the needs of water resources assessment with multiple temporal and spatial scale coordination. |
